Laggy servers

Anyone else see extreme lag in recent halo 5? Also, cant load into a game when in a fireteam. One of us always gets kicked.

At the time you were posting there was a service alert out for Xbox Live, it was affecting multiple games. It’s still actually up right now, be sure and keep an eye out on the support page for more details
